Discovering a new well: Decaying dark matter with profile likelihoods
Emil Brinch Holm, Laura Herold, Steen Hannestad +2
A large number of studies, all using Bayesian parameter inference from Markov Chain Monte Carlo methods, have constrained the presence of a decaying dark matter component. All such…

Mukhanov-Sasaki equation in manifestly gauge-invariant linearized cosmological perturbation theory with dust reference fields
Kristina Giesel, Laura Herold, Bao-Fei Li +1
The aim of this article is to understand the role of dust reference fields, often also called clocks, on cosmological perturbations around a flat FLRW universe. We derive the Mukha…

Hard and bright gamma-ray emission at the base of the Fermi bubbles
Laura Herold, Dmitry Malyshev
The Fermi bubbles (FBs) are large gamma-ray emitting lobes extending up to in latitude above and below the Galactic center (GC). Although the FBs were discovered 8 years ago,…
